This application relates to an electronic device inspection device.

For electronic devices such as semiconductor devices, in order to inspect various electrical characteristics, it is necessary to bring an inspection contactor into contact with the electrodes in order to energize. At that time, if the height of the electrode of the electronic device as the test piece does not fall within the predetermined range, poor contact occurs between the contactor and the electrode, and accurate inspection cannot be performed.

It is a perspective view (FIG. 4A) of the inspection table in which the four contacts are arranged, and is a perspective view (FIG. 4B) of the inspection table in which four contacts are arranged. FIG. 5 is a perspective view (FIG. 5A) of the inspection table portion of the electronic device inspection device according to the first modification and a perspective view (FIG. 5B) of the inspection table portion of the electronic device inspection device according to the second modification.

As shown in FIG. 1A, the electronic device inspection device 10 according to the first embodiment is a mechanism unit having a contact 2 that forms a contact point with an electrode in order to measure the electrical characteristics of the semiconductor device 90 which is an inspection product. 1 and a control unit 6 for controlling a measurement operation are provided. An electrode (not shown) is formed on one surface (electrode arrangement surface 90fe: FIG. 2) of an electronic device such as a semiconductor device 90, and by energizing this electrode, measurement of various electrical characteristics is performed. It is configured in.

The mechanism unit 1 has a contactor 2 and an inspection table 3 to which one end (base 2b) of the contactor 2 is fixed and, for example, a jig (not shown) for holding the semiconductor device 90 is attached. In the inspection table 3, the portion for fixing the contact 2 is made of an insulating material such as an insulating substrate, and each contact 2 is provided with a terminal 3t for connecting to the wiring from the measuring unit 61. Further, as described in a modification described later, an instrument for temperature control or fixing of the semiconductor device 90 may be provided.

The contact 2 is made of a shape memory alloy such as a nickel titanium alloy and is formed in the shape of a long thin plate. Then, as shown in FIG. 1B, one end side is fixed to the upper surface 3ft of the inspection table 3 and the other end side is reversibly changed from a spiral shape to a flat shape or a curved shape in the opposite direction due to a temperature change. It is composed of a variable portion 2a that changes and forms a contact point with the above-mentioned electrode.

As shown in FIG. 2, the base portion 2b is fixed to the upper surface 3ft with the axis of the spiral parallel to the electrode placement surface 90fe so that the spiral variable portion 2a rises from the surface 3ft toward the electrode placement surface 90fe. ing. That is, the base portion 2b is fixed to the upper surface 3ft away from the electrode arranging surface 90fe so that the variable portion 2a swirls in the direction approaching the electrode arranging surface 90fe. At that time, with respect to the electrode arrangement surface 90fe of the positioned semiconductor device 90, the side of the spiral variable portion 2a close to the electrode arrangement surface 90fe is directed from the inside to the outside in the direction toward the free end 2ae. It is fixed to the inspection table 3. As a result, when the spiral of the variable portion 2a develops due to the temperature change, the free end 2ae faces the outside of the electrode arrangement surface 90fe.

The length of the spiral portion needs to be long enough to connect even if there is a gap between the contact 2 and the electrode surface when the shape is restored. For example, in consideration of the manufacturing error in the height direction between the electrode surface and the contactor 2, it is necessary to have a length for securing the deformation amount and the contact area required for generating the pressing force due to the elastic deformation described later.

The control unit 6 outputs a measurement unit 61 that measures electrical characteristics by passing a current through the inspection product, an inspection control unit 64 that controls the entire inspection operation, an inspection result management unit 65 that manages inspection results, and an inspection result. It includes an inspection result output unit 66 and a data storage unit 67 for storing data. Further, for example, a temperature adjusting unit 63 for changing the shape of the contact 2 and a holding mechanism control unit 62 for controlling a mechanism for holding the inspection product may be provided, which will be described in a modification described later.

Details will be explained based on the above-mentioned configuration. When the semiconductor device 90, which is an inspection product, is installed on the inspection table 3, the contactor 2 at room temperature has a spiral shape, and as described above, the side close to the electrode arrangement surface 90fe is inside in the direction toward the free end 2ae. Towards the outside. At this time, since there is a gap between the variable portion 2a and the electrode arranging surface 90fe, the semiconductor device 90 uses a jig (not shown) with respect to the inspection table 3 without being interfered by the contactor 2. It can be easily positioned.

In this state, when the temperature of the contact 2 is raised, the variable portion 2a expands from the spiral shape, and as shown in FIG. 3, the portion of the electrode arrangement surface 90fe that hits an electrode (not shown) is along the electrode surface. It is deformed into a U shape and forms a contact region Rc with the electrode surface. In a high temperature state, the originally flat portion elastically deforms and acts as a spring, so that the variable portion 2a generates a pressing force on the electrode surface and is good between the contact region Rc and the surface. Electrical connection is possible.

That is, by utilizing the deformation due to the shape memory, it is possible to accurately position and inspect the semiconductor device 90 without being interfered by the contactor 2. Further, even if the semiconductor device 90 is installed at an angle or the electrode surface is inclined, the variable portion 2a is deformed along the inclined electrode surface and a pressing force can be applied, so that the variable portion 2a can be efficiently and accurately installed. Allows inspection of electronic devices.

If a contact is formed using a bimetal that deforms due to the difference in the coefficient of linear expansion, it is possible to change between spiral and flat depending on the temperature. However, in that case, although it acts as a spring due to the change in curvature, it becomes difficult to deform in the direction intersecting the bending direction, and there is a possibility of uneven contact with the tilted electrode surface. It is difficult to form Rc. On the other hand, the contactor 2 formed of the shape memory alloy can be deformed not only in the bending direction but also in the direction intersecting the bending direction, and good contact is possible by the deformation along the electrode surface. It becomes. Therefore, the contact resistance is small, accurate measurement can be performed, and the pressure is dispersed, so that the electrode surface of the semiconductor device 90 can be suppressed from being damaged.

In the above example, an example is shown in which the normal temperature is spiral and the high temperature recovers flat, but the shape is not limited to this. For example, if a shape memory alloy that recovers its shape at room temperature is used for the contactor 2, when the semiconductor device 90 is installed at a high temperature, the above-mentioned spring does not act, so that the contactor 2 does not cause interference such as pushing back. , Can be positioned accurately. Then, by cooling the contact 2 to a temperature at which the shape is restored, a good contact region Rc is formed, and accurate inspection becomes possible.

Further, the number of contacts 2 installed on the inspection table 3 is not limited to two, and as shown in FIG. 4 (FIGS. 4A and 4B), one or four contacts, a test piece, or a test. Any number may be used according to the content. On the other hand, considering the above-mentioned interference by the contacts 2, the effect of facilitating the positioning according to the present application is exhibited as the number of contacts 2 increases.

First modification example.
As shown in FIG. 5A, a stopper, a pressurizing tool, or a movement preventing tool 4 such as a heavy stone is installed in order to prevent the semiconductor device 90 from being dragged and moving when the contact 2 recovers its shape. You may do so. At that time, the inspection control unit 64 may monitor the progress of the measurement by the measurement unit 61, and the holding mechanism control unit 62 may control the drive and release of the movement preventive tool 4. With this configuration, the contact pressure between the recovered contact 2 and the semiconductor device 90 increases, so that the electrical connection becomes more reliable, and replacement with the next inspection body can be performed quickly. Therefore, the inspection efficiency is high.

Second modification example.
Further, the mechanism for changing the temperature of the contact 2 can be realized by raising the atmosphere temperature by bringing a heat source such as a dryer closer to the contact 2 or putting the test piece in a constant temperature bath or the like. good. Further, for example, as shown in FIG. 5B, a thermomodule 5 such as a Pelche element may be arranged in the vicinity of the contactor 2. At that time, the inspection control unit 64 monitors the progress of the measurement by the measurement unit 61, and causes the temperature adjustment unit 63 to control the temperature rise and cooling by the thermo module 5, the on / off of the dryer, or the loading and unloading of the dryer into the constant temperature bath. You may do so. In particular, when the inspection is performed at a high temperature, it is suitable because the temperature at the time of inspection can be accurately controlled by making the temperature rise and cooling into a process.

Embodiment 2.
In the first embodiment, the height relationship between the contact and the inspection table was not mentioned. In the second embodiment, an example in which the contactor is configured to be accommodated in the groove of the inspection table will be described. FIG. 6 is for explaining the electronic device inspection apparatus according to the second embodiment, and is a perspective view (FIG. 6A) of an inspection table portion and a schematic view (FIG. 6B) shown in a three-view format. The movement of the contact is the same as described in the first embodiment, and the form of the entire electronic device inspection device and the contact itself is shown in FIG. 1, when the contact recovers its shape and forms a contact region. FIG. 3B is used for the shape of.

As shown in FIG. 6, the electronic device inspection device 10 according to the second embodiment has a recess from the mounting surface 3ft1 on which the semiconductor device 90 is mounted on the inspection table 3, and a groove portion 3g corresponding to each of the contacts 2. Was set up. Then, the base portion 2b of the contact 2 is fixed on the bottom surface 3ft2 of the groove portion 3g, and the contactor 2 is placed between the mounting surface 3ft1 and the bottom surface 3ft2 when the variable portion 2a has a spiral shape. Contained inside.

In the inspection table 3, the wall surface of the groove 3g portion is also formed of an insulating material, and contacts 2 connected to terminals 3t (not shown) are arranged therein. When the semiconductor device 90 is installed on the mounting surface 3ft1 of the inspection table 3, the variable portion 2a is not in contact with the contactor 2 and is not electrically connected in the spiral state. However, by raising the temperature to a temperature at which the shape is restored, the contact 2 is deformed along the electrode surface of the semiconductor device 90 and is electrically connected by forming the contact region Rc, as in the first embodiment. NS.

Since the semiconductor device 90 is installed on the mounting surface 3ft1 of the inspection table 3 itself, the parallelism between the electrode arrangement surface 90fe and the bottom surface 3ft2 is higher than in the case of using a jig or the like, and the shape of the contact 2 is restored. The accuracy of electrical connection is improved. Further, the contact 2 can be electrically connected to the electrode of the semiconductor device 90 by raising the temperature of the contact 2 at an arbitrary timing. Therefore, when the semiconductor device 90 is installed, it is possible to suppress the generation of electrostatic discharge due to the charging of the human body, and it is possible to protect the semiconductor device 90.

Further, since the contact 2 is housed in the groove 3 g, the side surface of the groove 3 g acts as a guide, and when the contact 2 recovers its shape, it deforms along the side surface. Therefore, if the width of the groove 3g is aligned with the width of the electrode of the semiconductor device 90, the contact 2 can be prevented from being displaced from the electrode when it is deformed, and can be more reliably electrically connected. Further, since the semiconductor device 90 is in contact with the mounting surface 3ft1, there is no physical load when pressing the contactor 2 at the time of installation, and even when the semiconductor device 90 generates heat, the heat dissipation of the inspection table 3 is high. Therefore, the thermal load on the contact 2 and the semiconductor device 90 is reduced. This is particularly effective when an electronic device with a large calorific value is used as an inspection product.

When a plurality of contacts 2 are adjacent to each other along the long direction, it is conceivable that the contacts 2 may come into contact with each other when the shape is changed, and an unintended portion may be conducted, making accurate inspection impossible. .. However, if the partition 3s that partitions the groove 3g is provided, the contacts 2 do not come into contact with each other and become conductive in the process of changing the shape.

Needless to say, even when the groove portion 3g is provided, the movement preventive device 4 and the thermo module 5 may be provided as described in the first modification and the second modification of the first embodiment.

Embodiment 3.
In the second embodiment, the positioning configuration of the semiconductor device in the direction parallel to the mounting surface is not mentioned. In the third embodiment, an example in which a socket capable of positioning and fixing the semiconductor device is provided will be described. FIG. 7 is for explaining the electronic device inspection apparatus according to the third embodiment, and is a perspective view (FIG. 7A) of an inspection table portion and a schematic view (FIG. 7B) shown in a three-view format. Also in the third embodiment, the movement of the contactor is the same as that described in the first embodiment, and the form of the entire electronic device inspection device and the contactor itself is shown in FIG. 1, and the shape of the contactor is restored. FIG. 3B is used for the shape when the contact region is formed.

As shown in FIG. 7, the electronic device inspection device 10 according to the third embodiment is provided with a socket 31 into which the semiconductor device 90 is fitted in the inspection table 3. The socket 31 has a groove portion 3g for accommodating the contact 2 described in the second embodiment, a mounting surface 3ft1 on which the semiconductor device 90 is mounted, and supports four side portions of the rectangular plate-shaped semiconductor device 90. A frame-shaped portion 31c is formed.

The wall surface of the groove portion 3g provided in the socket 31 is also formed of an insulating material, and contactors 2 connected to terminals 3t (not shown) are arranged therein. When the semiconductor device 90 is installed on the mounting surface 3ft1 in the frame-shaped portion 31c of the socket 31, the variable portion 2a is not in contact with the contactor 2 and is not electrically connected in the spiral state. However, by raising the temperature to a temperature at which the shape is restored, the contact 2 is deformed along the electrode surface of the semiconductor device 90 and is electrically connected by forming the contact region Rc, as in the first embodiment. NS.

At that time, since the four side portions adjacent to the electrode arranging surface 90fe in the rectangular plate-shaped semiconductor device 90 are supported by the frame-shaped portion 31c, positioning in a direction parallel to the electrode arranging surface 90fe can be easily performed, and the above-mentioned It is possible to prevent misalignment even when a force is applied during shape recovery. Further, as described in the second embodiment, the parallelism between the electrode arrangement surface 90fe and the bottom surface 3ft2 is high, and the accuracy of electrically connecting the contactor 2 when the shape is restored is improved. Further, the contact 2 can be electrically connected to the electrode of the semiconductor device 90 by raising the temperature of the contact 2 at an arbitrary timing. Therefore, when the semiconductor device 90 is installed, it is possible to suppress the generation of electrostatic discharge due to the charging of the human body, and it is possible to protect the semiconductor device 90.

Further, since the contact 2 is housed in the groove 3 g, the side surface of the groove 3 g acts as a guide, and when the contact 2 recovers its shape, it deforms along the side surface. Therefore, if the width of the groove 3g is aligned with the width of the electrode of the semiconductor device 90, the contact 2 can be prevented from being displaced from the electrode when it is deformed, and can be more reliably electrically connected. Further, since the semiconductor device 90 is in contact with the mounting surface 3ft1, there is no physical load when pressing the contactor 2 at the time of installation, and even when the semiconductor device 90 generates heat, the frame-shaped portion 31c also serves as a heat dissipation path. Since it functions, the heat dissipation is higher than that of the second embodiment, and the thermal load on the contact 2 and the semiconductor device 90 is reduced. This is particularly effective when an electronic device with a large calorific value is used as an inspection product. Further, the socket 31 is detachably fixed to the inspection table 3 by screwing or the like, so that even if the semiconductor device 90 is burnt out, other parts can be reused by replacing the socket 31.

Further, even when the socket 31 is used, when a plurality of contacts 2 are lined up in the same direction, the contacts 2 come into contact with each other when the shape changes, and an unintended portion becomes conductive, which makes accurate inspection impossible. Can be considered. However, if the partition 3s that partitions the groove 3g is provided, the contacts 2 do not come into contact with each other and become conductive in the process of changing the shape. Needless to say, even when the socket 31 is provided, the movement preventing tool 4 and the thermo module 5 may be provided as described in the first modification and the second modification of the first embodiment.

In the electronic device inspection device 10 according to each embodiment, for example, the portion that executes the calculation or control of the control unit 6 is a hardware composed of the processor 601 and the storage device 602 as in the example shown in FIG. It can be described as wear 60. The storage device 602 includes a volatile storage device such as a random access memory (not shown) and a non-volatile auxiliary storage device such as a flash memory. Further, the auxiliary storage device of the hard disk may be provided instead of the flash memory. The processor 601 executes the program input from the storage device 602. In this case, the program is input from the auxiliary storage device to the processor 601 via the volatile storage device. Further, the processor 601 may output data such as a calculation result to the volatile storage device of the storage device 602, or may store the data in the auxiliary storage device via the volatile storage device.

Further, a case where the variable portion 2a forms a spiral shape and is spaced from the electrode is shown as a preferable example, but it is not always necessary to space the variable portions 2a, and they are in contact with each other unless an excessive repulsive force is generated. You may.

It can be inspected efficiently and accurately.
